Is there a standard (such as IPC) or common industry practice in regards with x-out marking on rejected boards of a panel? Do board shops have to X-out both sides of the rejected board, or one side? If the answer is one side, which side should be ma

There is no standard. You need to decide when you want the cost of bad boards applied to your product cost. Search the fine SMTnet Archives for previous discussions, like: http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=20871

1.0 X-OUT POLICY 1.1 Each Panel not to contain in excess of X% X'd-Out boards. 1.2 Each X-Out board to be marked in a manner so that Pick & Place equipment will not attempt to insert those boards X'd-Out such as fiducial reference hole for paneliz

Are there recommended image reject marks in order to process x-outs from a PCB supplier? Do they have to be in the copper or will silkscreen suffice?

Here's a link to an earlier thread on SMTnet that may add something to the conversation http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=20871 Allowing fabricators to X-Out boards is a bad idea. * X-Outs are randomly placed * Machines can

Yes X-outs impact cycle times. Firstly, unless your board house is adding the bad marks you have the added labor of doing it yourself and programming your machines to look for them. Additionally, it adds time to each machine in the line (except for s

1: I use the fiducial mark as bad board mark. 2: First get the X sensor installed on the machine, then use method 1. 3: other methods: group boards according to which unit is X out. Then edit NC program to skip corresponding X out.

I've been reading the forum here for a few weeks and found some helpful material from talented individuals. Now, I have a question(s). I'm looking into different alternatives for doing X outs. Right now I'm familiar w/ two of them:1. Bad Board Mar

I don't have our DEK printer part numbers memorized, In general we have a older machine running NT4.0 . It has 2Di inspection but we never use it because you can only inspect/setup 1 camera shot at once, making for very long programming. Our newer D

Thank you for your advice Eric. Different SMT Machine Platforms have different methods for handling these PCB Panels with bad circuits. (Commonly known as "X-outs"). Some platforms allow you to identify X-Outs simply by darkening in the first fid
